Embodiment 1
[0036] A preparation method of an edible casing film blended with collagen fibers and starch, specifically comprising the steps of:
[0037] 1) Cowhide splitting, soaking mortar:
[0038] Take 1000kg of untreated fresh cowhide (cow's split hide), wash the cow's split hide with water, then cut it into 100mm×100mm blocks with a cutting machine, and use 150kg of food-grade calcium hydroxide (slaked lime) ) pulp (water: calcium hydroxide = 1:2, mass ratio) marinated for 6 days (commonly known as soaking mortar); wash away the calcium hydroxide, and then rinse it repeatedly with water for 5 times, and wash the pH value of the skin to 8 , and then use alkaline protease to further degrade the treatment. The treatment method is: put the leather into water, the mass ratio of leather and water is 1:2, and then add alkaline protease in an amount of 0.5‰ of the leather mass. Soak at 20°C for 2 hours, under the action of enzymes, the collagen fibers in the cowhide are degraded in a short ti...
Embodiment 2
[0054] A preparation method of an edible casing film blended with collagen fibers and starch, specifically comprising the steps of:
[0055] 1) Cowhide splitting, soaking mortar:
[0056] Take 1000kg of untreated fresh cowhide (cow's second layer hide), wash it with water, then cut it into 100mm×100mm blocks with a cutting machine, and use 150kg of food-grade calcium hydroxide (slaked lime) slurry (water: Calcium hydroxide = 1:2, mass ratio) marinate for 7 days (commonly known as soaking mortar); wash off the calcium hydroxide, and then rinse it repeatedly with water for 4 to 5 times, and wash the pH value of the skin to 9. Then use alkaline protease to further degrade the treatment. The treatment method is: put the leather into water, the mass ratio of leather and water is 1:2, then add alkaline protease, the addition amount is 1.0‰ of the leather quality, at 25 Soak at ℃ for 1 hour, under the action of enzyme, the collagen fibers in the cowhide are degraded in a short time,...
Embodiment 3
[0072] A preparation method of an edible casing film blended with collagen fibers and starch, specifically comprising the steps of:
[0073] 1) Cowhide splitting, soaking mortar:
[0074] The cow split skin is washed with clean water, then cut into 100mm×100mm blocks with a dicing machine, and marinated with food-grade calcium hydroxide (slaked lime) slurry (water:calcium hydroxide=1:2, mass ratio) 10 days (commonly known as foam mortar); wash away the calcium hydroxide, and then rinse it with water for 4 times, and wash the pH value of the skin to 8.5. Then use alkaline protease to further degrade the treatment. The treatment method is: put the leather into water, the mass ratio of leather and water is 1:2, then add alkaline protease, the addition amount is 0.5‰ of the leather quality, at 30 Soak at ℃ for 1 hour, under the action of enzyme, the collagen fibers in the cowhide are degraded in a short time, the fibers become loose, the interfibrous matrix and impurities are rem...
